hello, i have a lenovo thinkpad P43s that exhibits lockups under CURRENT but behaves fine when running STABLE. i've tried to find a fully reproducible situation to get this system to lockup but haven't found anything yet. i am starting to suspect that the changes implemented in this review may be the issue though: https://reviews.freebsd.org/D23728 my reasoning is that i've observed issues when: - removing AC power from the laptop, or inserting AC power - when the system display has gone to sleep - randomly hanging during boot with this as last line: battery0: battery enitialization start unfortunately while the above seem to be cases where this has happened i haven't been able to %100 reproduce yet. so my first question is - would it be possible to just revert the changes in that diff, or has too much time gone past to just back out that single change. alternatively, is there any debugging information i can get on my end that might help figure out what the root cause is? cheers, -pete -- Pete Wright pete_at_nomadlogic.org _at_nomadlogicLAReceived on Mon May 11 2020 - 20:16:17 UTC
